# =============================================================================
# https://www.gnu.org/software/autoconf-archive/ax_create_pkgconfig_info.html
# =============================================================================
#
# SYNOPSIS
#
# AX_CREATE_PKGCONFIG_INFO [(outputfile, [requires [,libs [,summary [,cflags [, ldflags]]]]])]
#
# DESCRIPTION
#
# Defaults:
#
# $1 = $PACKAGE_NAME.pc
# $2 = (empty)
# $3 = $PACKAGE_LIBS $LIBS (as set at that point in configure.ac)
# $4 = $PACKAGE_SUMMARY (or $1 Library)
# $5 = $PACKAGE_CFLAGS (as set at the point in configure.ac)
# $6 = $PACKAGE_LDFLAGS (as set at the point in configure.ac)
#
# PACKAGE_NAME defaults to $PACKAGE if not set.
# PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set.
#
# The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc
#
# You will find this macro most useful in conjunction with
# ax_spec_defaults that can read good initializers from the .spec file. In
# consequence, most of the generatable installable stuff can be made from
# information being updated in a single place for the whole project.
